here's what I found on Pygmy Gouramis.
They are shy fish and it is recommended to keep them only with their own kind. It is not recommended to keep them in a large aquarium. They can eat prepared foods or small live foods.
You may not be able to determine the sex of the fish . They love warm temperatures and are very fragile if it is not kept warm.
They are bubblenest breeders (related to Bettas - don't even think of putting them together) and can be easy to breed if the right pair are acquainted, but very difficult if they decide they don't care for each other. Sometimes it works quite well and sometimes not at all. Males care for fry and they hatch in about 30 hours.
All this information came from but was not quoted from:
Aquarium Fishes of the World by Dr. Herbert Axelrod, Dr. Warren E. Burgess, Glen S. Axelrod, David E. Boruchowitz
